- You cannot do cross-domain tracking of a user. You will not be able to track the same user on both http://www.example.com and http://example.com. A single user visiting both of these will result in two unique users.
- You cannot do cross-scheme tracking of a user. You will not be able to track the same user on both https://www.example.com and http://www.example.com. A single user visiting both of these will result in two unique users.

- Install the ga-localstorage package (optionally saving it to your package.json):
- `npm install ga-localstorage --save`
- `var analyticsSnippet = require("ga-localstorage")("UA-8675309-1");`
- Do whatever you want with it.
- you should probably output it between a `<script>` and a `</script>` right before `</body>`.
